Research Visit from UNSW Sydney

2 November 2026

In October, the QuSAC Lab welcomed three visitors from the University of New South Wales (UNSW Sydney): Associate Professor Sushmita Ruj, PhD candidate Varpreet Singh Dhaliwal, and student Joseph Hilsberg.

During their research visit, we worked together on the design, implementation, and benchmarking of anonymous credential systems built from digital signature schemes and generic proof systems. Anonymous credentials allow users to prove specific attributes without disclosing unnecessary personal information.

A particular focus was placed on post-quantum security and features that are important for practical deployment. These included the secure revocation of previously issued credentials and issuer hiding, which protects information about the issuing authority. In addition to the cryptographic foundations, we investigated the efficiency and practical feasibility of different approaches while considering the threat posed by future quantum computers.

The visit provided an excellent opportunity for in-depth discussions and an exchange of ideas between the visitors from UNSW Sydney and researchers from across RI CODE. We thank Sushmita, Varpreet, and Joseph for the productive time together and look forward to continuing our collaboration.
